Patented March 13, 1906.

Application filedAugust 1 p1905, Serial No. 274,293 I To-all whom it mdyi'eo ncern;

Be it known that I, HEO RE'C. LAMOUF REUX, a citizen of the United States, residing at Lu-ton, in the county of Woodbury and State of Iowa,haveinvented certain newand useful Improvements in Draft-Equalizers, of which the following is a specification.

i This invention relates to improvements draft equalizers, andhas for its object to roducea device of this character which wil be free from all side draft, which will be simple and durable construction, and which can knowledge of the details of'construction of. the meanslfor effecting the result reference is tobe had to the following description and accompanying drawings, in which Figure 1 is-atop plan view of a draft-equalizer embodying my invention. Fig. 2 1s a perspective-view-of the attachment which is.

secured'to the-tongue in the rear of the main lever Fig. 3-isaperspectiveview of a modi fied form of attachment. Fig. 4 is a perspective view of themain lever, showing the" methodof 'constructing'same out of two.

spaced members. Fig. 5 is atop plan View of a draft-equalizerconstructed according to my invention and showing a modified form of the attachment which is especially adapt- 1 ed for'use in connection withplows. Fig. 6 Q

is'a perspective view of the modified form of attachment. Y

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters;

The numeral 1 designates the tongue, and 2 the lever, which is pivoted thereto by means of a pin 3 so as to form a long arm 4 and a short arm 5, said long arm being preferably about twice the length of the short arm. The lever 2 is formed out of two spaced members, which have a number of pulleys mounted be- I tween them. The attachment SliOWIll-lilfFlg.

2 is secured to the tongue immediatelyin the rear of the lever 2. attachment is apone leg ofwhichifis secured to the tongue, while the other two sides project outwardly on the same side of the tongue 1 as the short 2, around the pulleys 10. and ,l l on the hypotenuse 12 and" the leg 6 of the; triangular attachment, and aroundthe pulley'l'3 on the the tonguel by means." of the hook 'A similar cable 15 isattachedto the doubl'etree 16 and passes between pulleys 17 onthe long arm 4,around the pulley 1 8 on'the hypotesecured to the short arm 5% 19', It will thus be seen that the three horses hitched to the doubletree 16 pull backward upon the short arm 5 of the lever2 at 19 and that owing the single horse hitched to the swingletree 8 pulls backward upon the extremityj'of the ong arm 4 with. a force equal to that. of

'3 and the point 19 and between said pivot and the pulley'13 can be so adjusted as to es of the tongue 1'.

pulleys this device can be adjusted so @Sto serve either as a one, two, three, four, or five horse evener. When used with two or three horses, the attachment shown in Fig. 3' may ment shown in 2. This attachment simply comprises two spaced members 20, hav" ing' pulleys 21 mounted between them, aroundwhich the cables 7 and 15' areipassejd.

cables around pulleys secured in same, all side draft'iseliminated;

A modified form of the attachment is shown in Figs. 5 and '6, which is particularly adapted for use. in connection with lows. When this modification is employed? four horses can be attached to the plow Without necessitating the walking upon the upturned earth by any of them, one of the arm 5 of the lever 2. Y A cable 7, which at tached to the swingletree 8, passes'between two pulleys 9 on the short. arm 5 ofthelever Owingto the peculiar construction .of'these attachments and the method of passing the proximately in the shape of a right triangle, 1

extremity of the long-arm 4 of thele'ver2, the endof the cable 7 being secured1tothe rear of nuse I2 of the triangular attachment, and is to the fact that a double pulley is formed two horses. The, distance between the'pivot ecpualize the pull of the horses on opposite s1 By changingthe positions of the various be employed instead of the triangular attachv v horses walking in the furrow While the other three are upon the solid ground which has not been plowed. This modified form of attachment comprises two arms 22 and 23, which are rigidly connected to each other and are each formed of two spaced parts, having guide members mounted between them. One of the arms 22 extends along and is secured to the rear portion of the tongue, while the opposite arm 23 projects from one side of the tongue and extends obliquely toward the front thereof, The equalizing-lever 24 is formed of spaced members, as in the previous instance, and is pivoted at an intermediate point to the free end of the arm 23. The long arm of this equalizing-lever crosses the tongue and extends on the opposite side thereof to the arm 23 of the attachment. The single horse is attached to a cable 25, which asses between pulleys 26 at the end of the ong arm of the lever 24, said cable then passing around a pulley 27 at the intersection of the two arms of the attachment, and has its end fastened to the short arm of the equalizing-lever at 28. The three horses on the opposite side of the tongue are attached to a similar cable 29, which passes between pulleys 30 on the short arm of the lever, around pulleys 31 and 32 upon the two arms of the attachment, and has its end secured at 33 to the long arm of the lever. By this arrangement the one horse is given a sufiicient amount of leverage to equalize the pull of the three horses and all side draft is eliminated.

Having thus described the invention, what is claimed as new is- 1. In a draft-equalizer, the combination of a tongue, an equalizing-lever having a long arm and a short arm, a member extending longitudinally along the tongue in the rear of the equalizing-lever, said member being detachably connected to the tongue andformed of spaced members having a guide member mounted between them, an obliquely-disposed bracket rigidly secured to and project ing from said member, said bracket being formed of spaced parts having a guide member mounted between them, a cable connected to the single horse and passing through guide members on the short arm of the lever, a second cable connected to the plurality of horses on the opposite side of the tongue and passing through guide members on the long arm of the lever, said cables passing around the guide members on the obliquely-disposed bracket and longitudinal member and having their ends rigidly fastened.

2. In a draft-equalizer, the combination of a tongue, an equalizing-lever having a long arm and a short arm, a longitudinal member extending along the tongue in the rear of the equalizing-lever and formed of spaced parts having a guide member mounted between them, an obliquely-disposed bracket projecting from the longitudinal member and also formed of spaced parts having guide members mounted between them, a brace member for the obliquely-dis osed bracket, a cable connected to the sing e horse and passing through guide members on the short arm of the lever, the bracket, the longitudinal member, the long arm of the lever, and having its extremity secured to the tongue, and a second cable connected to the plurality of horses on the opposite side of the tongue and passing through guide members 011 the long arm of the lever and the bracket, the end of the second cable being secured to the short arm of the lever.

3. In a draft-equalizer the combination. of

a lever pivoted. upon the tongue and having a long arm and a short arm, an attachment secured to the tongue in the rear of said lever, said attachment being triangular in shape, each side of the triangular attachment comprising two spaced parts having guide members mounted between them, one of the sides extending along the tongue while the other sides project outwardly on the same side of the tongue as the short arm of the lever, a cable connected to the single horse and passing through guideways on the short arm of the lever and the outwardly-projecting portion of the attachment, said cable then passing around a pulley on the long arm of the lever and having its extremity secured to the tongue, a second cable attached to the plurality of horses on the opposite side of the tongue and passing tlnough guide members on the long arm of the lever and the attachment, and having its end secured to the short arm of the lever.
